Item # AS7284, Air Shower (AS Series)

Clean Room Depot’s (AS Series) air showers and tunnels are self contained chambers designed to effectively remove particulate contamination from personnel before entering the clean room. Each air shower or tunnel supplies high velocity air streams of Class 100 HEPA filtered air through adjustable nozzles which lift off contaminates while an individual stands in or walks through the chamber. The nozzles are strategically arranged on the walls and ceiling to direct contaminated air downward through pre-filtered grilles and hollow wall returns and back to the HEPA filter which is 99.99% efficient at removing particles at 0/3 microns and larger. Maintenance and filter replacement are simplified and performed primarily from outside to minimize downtime during servicing. Units are available in (9) standard straight thru configurations as well as custom right and left turns and 2 & 3 way entry systems. All air showers and tunnels meet federal, military and industrial specifications for air showers used for pharmaceutical, aerospace, electronic, biomedical and other precision manufacturing applications.
